STYLOGRAPHIC PEN.

Application filed October 7, 1910. Serial No. 585,780.

Specification of Letters Patent.

1 two diametrically disposed grooves 18, duct is also diametricallyarranged, its axis coinciding substantially with a line connecting thegrooves. A tubular plug 21 removably fitted into the upper end of nozzle12, prevents an undue longitudinal movement of the bar, withoutimpairing a free flow of ink from the holder toward the same.

In use, the ink will flow downward along longitudinal grooves 18, andfill circumferential groove 19, as well as duct 20. This groove togetherwith the duct will thus form supply pockets from which the ink is at alltimes freely delivered over coniform head Be it known that I, JACOBUnnnion, a citizen of the United States, residing at Hoboken, county ofHudson, and State of New Jersey, have invented certain new and usefulImprovements in Stylographic Pens, of which the following is aspecification.

This invention relates to a stylographic pen of novel construction, andmore particularly to novel and eflicient means for supplying the stylowith an ample charge of ink and insuring the necessary air pressure inall positions that the pen may assume during writing.

15 In the accompanying drawing: Figure 1 16* to the stylo in amplequantity.

is a plan of a stylographic pen embodying The correlation of the partsis such that my invention; Fig. 2 an enlarged longituvent 15 is alinedwith and opens into cirdinal section through the lower parttherecumferential groove 19, so that. at all posiof; Fig. 3 aperspective view of the ink feed tiOnS of the-bar, the air may freelyascend 2 bar, and Fig. 4 an enlarged end view of the through saidgroove, and through the then nozzle. uppermost longitudinal groove 18,into the To the lower end of the tubular holder 10, holder 1 t0fllllllsh the necessary Pressureis connected by a screw joint 11, anozzle 12, I clalmf I that carries the usual tubular metal tip 13. Astylogl'aphlc P P I P a 5 Th upper ti f nozzle 12 overhangs holder, anozzle, and a feed bar within the nozzle, said bar being provided with atapering head, a longitudinal groove, a communicating lowercircumferential groove, and a transverse duct opening at both ends thelower section to form a downwardly opening circumferential groove 14,into which opens a vent 15. The stylo or needle 16, which projectsthrough tip 13 is secured to the lowe coniform head 16 of a freely intothe circumferelltifll movable feed bar.17, said head finding a Astylogmphlc P pr p bearing against an inner tapering wall of holder, anozzle, and a feed bill Wlthln the lower nozzle section. The stem ormain body of bar 17, is provided with a suitable number of longitudinalsurface grooves '18, two diametrically disposed grooves being shown. Attheir upper ends, these grooves extend to the top of the bar while theirlower ends communicate with a circumferential surface groove 19 of thebar formed directly above head 16*. Finally there extends through thebar a transverse duct 20, opening at bothends into groove 19 oppositethe lower ends of grooves 18. Thus with nozzle, said bar being providedwith a tapering head, a pair of diametrically disposed longitudinalgrooves, a communicating lower circumferential groove, and a transverseduct that enters the circumferential groove and connects the lower endsof the longitudinal grooves.
